CompTIA A+ Core 2 (220-1102) — Question 151

A user is unable to access files on a work PC after opening a text document. The text document was labeled “URGENT PLEASE READ.txt - In active folder, .txt file titled urgent please read”. Which of the following should a support technician do FIRST?

Answer options

• A. Quarantine the host in the antivirus system.
• B. Run antivirus scan for malicious software.
• C. Investigate how malicious software was installed.
• D. Reimage the computer.

Correct answer: B

Explanation

The correct approach is to run an antivirus scan for malicious software as the first step to identify and address any potential threats. Quarantining the host or investigating the installation method are later steps that would follow the immediate threat assessment. Reimaging the computer is a more drastic measure that should only be considered if the issue cannot be resolved through simpler means.
